Origin

Nowadays a can is a cylindrical metal container, but its ancestor, Old English cann, was a general word for any container for liquids. It may come from Latin canna ( see cannon). If someone carries the can they take responsibility for a mistake or misdeed. The origin of this expression is uncertain, but it probably started life as early 20th-century naval slang. One theory is that it refers to the beer can or keg which one sailor carried for all his companions. An early version was to carry the can back, which might have referred to returning the empties. In film-making and recording you can talk about something being in the can when it has been captured on tape or film to a satisfactory standard. Though videotape and digital recordings are not stored in cans, the older expression has been transferred to them. See also worm, cunning, know
